SPECIAL TRAITS

• Distracting Swarm. The swarm can occupy another creature’s space and vice versa, and the swarm can move through any opening large enough for a medium aberration. The swarm can’t regain hit points or gain temporary hit points. Additionally, creatures sharing the same space as a swarm are distracted. They gain disadvantage on all attack rolls and ability checks (but not saving throws).
• Innate Spellcasting (Psionic). As above. Powerful Mind. As above.
• Steal Body. As above.

ACTIONS

• Multiattack. The ceroptor swarm makes three stinger attacks.
• Stinger. Melee Weapon Attack: +6 to hit, reach 0 ft., all creatures in the swarm’s space. Hit: 23 (6d6 + 2) piercing damage, or 12 (3d6 + 2) piercing damage if the swarm has half of its hit points or fewer. The target must succeed on a DC 15 Constitution saving throw or become paralyzed for 1 minute. The creature can make a new saving throw at the beginning of their turn, ending the effect on a success.
• Ganglion Probe. As above.
